Abstract
The invention discloses an engineering block and making craft at the raw material of stone powder, which is characterized by the following: preconditioning, dispensing, stirring, modeling and curing the stone powder to generate the block for building trades, which provides enormous economic and social benefit and reduces the pollution drainage.
Description
[technical field] the invention belongs to a kind of constructional materials and production and processing technology thereof, and particularly relating to a kind of is the building block and the manufacture craft thereof of making raw material with the stone flour.
[background technology] stone flour is the main discarded object in the processing of stone industry, and its growing amount is very big, and does not still have the approach that utilizes again at present.General way is to discharge on the spot, and therefore air and the water source environment to the locality causes severe contamination.On the other hand, along with greatly developing of China's infrastructure, demand to constructional materials increases day by day, and traditional constructional materials is to be taken from natural resource after all, therefore, a large amount of exploitations has expended natural resources such as many soils, the energy, and the strategic thought of the sustainable development of being advocated with current society is contrary.
[summary of the invention] purpose of the present invention promptly be to provide a kind of novel be the building block and the manufacture craft thereof of making raw material with the stone flour, to reach twice laid, turn waste into wealth, reduce environment pollution, saving utilizes resource, and obtains the purpose of certain economic benefit simultaneously.
Disclosed in this invention is the building block of making raw material with the stone flour, be meant pavior brick or hollow wall building block, it is characterized in that, be raw material with dryness stone flour, river sand, rubble and cement, makes through stone flour preliminary treatment, batching, stirring, moulding and maintenance.
Disclosed in this invention is the manufacture craft of making the building block of raw material with the stone flour, it is characterized in that may further comprise the steps:
Step 1: stone flour preliminary treatment; Collect the stone flour that contains certain moisture that is generated in the stone material sawing process, take the method for air dry or oven dry to make it dehydration, its moisture content is controlled at 6～12%, will lumps or be that spherical stone flour rolls, fragmentation then with the rolling mixer, stop during the powder that making it to be loose;
Step 2: batching; Prepare burden according to technical recipe; Disclosed in this invention is the building block of making raw material with the stone flour---the technical recipe of pavior brick is (by weight, down together): dryness stone flour 60～65%, river sand 5～10%, rubble 15～20%, cement 10～15%; Disclosed in this invention with the stone flour be make raw material building block---the technical recipe of hollow wall building block is: dryness stone flour 55～60%, river sand 5～10%, rubble 20～25%, cement 10～15%;
Step 3: stir; Utilize mixer that the compound for preparing is stirred, and add the index request that water makes it to reach the harsh concrete that forming machine is suitable for;
Step 4: moulding; Utilize forming machine and cooperate mould, it is building block---the pavior brick or the corresponding shape of hollow wall building block of making raw material with the stone flour that the material press process that stirs is become disclosed in this invention;
Step 5: maintenance; The product of press process moulding put into stream curing is indoor carries out maintenance, temperature is controlled at 60～70 ℃, and curing time is 5～6 hours; Then, leave standstill 2～3 hours after, be carried to outdoor parking again and got final product in 7～15 days.
Provided by the present invention is the building block and the manufacture craft thereof of making raw material with the stone flour, made full use of a large amount of discarded objects---the stone flour that the processing of stone industry is generated, and then make the used quality material of building trade, not only has considerable economic, and reduced of the disposal of pollutants of processing of stone industry to a great extent to environment, have good social benefit simultaneously.
[specific embodiment]
Disclosed in this invention is the building block of making raw material with the stone flour, can be pavior brick, also can be the hollow wall building block.Except that proportion scale slightly the difference, said two products is a raw material with dryness stone flour, river sand, rubble and cement all, and all processes through processing steps such as stone flour preliminary treatment, batching, stirring, moulding and maintenances.Therefore, be example with the hollow wall building block below, its manufacture craft is described in detail:
The stone flour that contains certain moisture that is generated in the stone material sawing process is collected,, adopt the method for forcing oven dry again, make its moisture content be reduced to 10% earlier through air dry.Then, roll and fragmentation, make it the powder that is loose with the rolling mixer.
According to the formula rate of dryness stone flour 60%, river sand 5%, rubble 20%, cement 15%, to prepare burden through proportioning machine, the Dynamic Weighting error is less than 1.5%, and each dosage is the rated capacity of mixer.
When stirring feeds intake, carry out according to order: at first, successively stone flour, rubble, river sand are put in the mixer, stir in advance earlier, drop into cement again and do stirring, then, add water gradually and carry out water filling and stir, stop after reaching the index request of the harsh concrete that forming machine is suitable for.Because of stone flour very easily condenses into spherically, doing the water content that needs to detect in real time mixed material when stirring, slow balanced water filling, and FEEDBACK CONTROL in good time." the microwave moisture measurement controller " and " JN series vertical shaft planetary mixer " that can adopt Britain to produce.Certainly also can adopt other similar model, its effect is the same.
Then, adopt forming machine again and cooperate the hollow wall building block mould, the material vibration press process that stirs is become the shape of hollow wall building block.Mixer can adopt " the desk-top forming machine of auspicious figure RTQT6 ".This type has overcome the low shortcoming of traditional hydrostatic profile compactness, has avoided the drawback of simple vibration moulding coarse-fine aggregate separation again, has the characteristics of working (machining) efficiency height, constant product quality.
At last, the hollow wall building block of press process moulding put into stream curing is indoor carries out maintenance, temperature is controlled at 65 ℃, curing time is 6 hours, left standstill again 2 hours, and can reach 60～70% early strength, can satisfy the requirement of a dead lift or mechanical pile, can be carried to outdoor stockyard and park this moment, can be delivered for use after 10 days.
